IMPRQVEMENT IN HORSE-POWERS.

Specification forming part of Letters Patent N 0. 133,546, datedDecember 3, 1872.

To all whom it may concern:

Be it known that I, WILLIAM SoHUYLnR,

of Oran geville, county of Columbia and State of Pennsylvania, haveinvented certain new and useful Improvements in Tread-Mill Horse-Powers, of which the following is a specification:

The nature of my invention relates to the construction of a tread-mill;and consists in the peculiar arrangement and construction of thegearing, which is so made that the power can be applied directly to themachine to be driven without the use of abolt; in the peculiar'construction of the brakes; and the manner of attaching the cross-piecesto the links so as to form the tread-mill, as will hereinafter be morefully set forth.

Figure 1 is a side elevation of my invention, and Figs. 2 and 3 detailedsectional views of the same.

. A 13 represent the frame, which may be constructed in any suitablemanner. The tread-mill consisting ofthe cross-bars O, linksD, androllers G, shown in Fig. 2, are of peculiar construction. The ends ofeach cross-bar O are bifurcated, one part passing through a slot made ineach link D, and the other part extending up over the top, as shown inFig. 3. By this construction the two parts are held securely togetherwithout being fastened by bolts, and can be readily taken apart and puttogether again. Each link consists of a slotted plate, having its endsmade'of a semi-spherical shape,

so as to fit in the recesses of the wheel H,

large flanged wheel J secured toits end. This wheel has its inner facecut by a series of cogs, into which the beveled gear or pinion K securedto the short shaft L meshes, and awide rim or flange, upon which thebrakes operate. The shaft L extends backward, and has its bearings on aplane with the frame, and to its rear end a tumbler or any suitableconnectinggear is secured, so that the power may be apdescribed, willoperate with less friction, run

more easily, and can be placed at an angle at from six to eight inchesless than those now in common use.

Bearing upon the rim of the wheel J are two brakes, 0, connectedtogether by bars It S and the upright bar P, and controlled by the leverQ.

The ordinary brakes, as applied to the tread mill, are seldom if eversuflicient to instantly stop the machine, and cannot always be reliedupon; but by the use of the double clamps upon a wide flanged wheel themotion can be checked or stopped at will.

Having thus described my invention, what I claim as new, and for which Idesire to se cure Letters Patent, is-

1. A tread-mill horse-power, in which the power is connected tothe'machine to be driven without the use of a belt, arrangedsubstantially as set forth.

2. In combination with a flanged wheel of a tread -mill horse-power, thedouble clamped brakes 0, bars R and S, connecting-bar P, and lever Q,when arranged to operate substantially as specified.

3. The combination of the cross-barsO, links D, wheels H J K, and shaftL, when all are combined to form a tread-mill horse-power, as shown anddescribed.

In testimony that I claim the foregoing as my invention I hereto affixmy signature.

XVILLIAM SGHUYLER.
